The Indian Grand Prix proved to be another fascinating tactical battle between teams and drivers, showing that there’s often more than one way to get the best out of a race situation.
When the teams ran in Friday’s free practice sessions, it quickly became clear that the two nominated tire compounds had vastly different characteristics. The soft tire, or option, delivered a lap time around a second faster than the medium, or prime, but deteriorated significantly within a handful of laps. The medium was slower, yet withstood the abrasive surface of the Buddh International Circuit and showed almost no signs of degradation or wear for long spells, even on heavy fuel loads.
This all meant that race strategy, even more so than normal, had to be planned out before qualifying on Saturday afternoon.
The two most obvious race strategies were to qualify, and therefore start the Grand Prix, on the faster option tire, run that for a short spell, before doing two long stints on prime to the end; or conversely qualify and start on prime, even though it meant taking a hit on lap time and therefore grid position, before another stint of the same and switching to the options right at the end of the race.
There wasn’t much on paper between the two, but in fact most simulations had the latter version coming out as being slightly quicker by four or five seconds over the course of the entire race. Both were therefore feasible options and a few teams chose to cover both bases and split their two drivers.
You might ask why, if one strategy shows up as being four seconds faster than another, doesn’t everyone just go with that one?
There’re many factors to be taken into consideration before deciding on race plans, some aren’t always obvious to the outside world.
First, teams need to look at their two drivers and pinpoint their individual strengths and weaknesses. If one driver is clearly better than the other at looking after tires, he could manage a longer stint on options, or even in extreme cases, look at one less stop than his teammate. We saw this in Japan between the two Red Bull drivers.
Another consideration is a driver’s ability to cleanly overtake the pack if he comes out into traffic after a pitstop. Again, we saw the difference between Sebastian Vettel and Mark Webber in Japan when both of their strategies needed them to catch and pass Romain Grosjean’s Lotus. Vettel did it quickly and cleanly, without losing time or hurting tires behind his rival. Webber spent two laps fighting under the Lotus’ rear wing and lost time on the track to his teammate, but took valuable life from his Pirellis, which meant his strategy failed.
The ability to deliver a qualifying lap late in the session, under pressure and without the need to do multiple runs will determine how many new sets of tires the team have to use in the race. This obviously has a big impact on strategy.
In India, those who qualified and started on options had already taken three laps of life from their tires before the race had even begun, those who were able to save options and then set Q3 times on primes, were able to keep a brand new set for the last race stint. On a circuit where soft tires only lasted a few short laps, that was where part of those four or five seconds difference would come from over the alternate race strategy.
The team know their drivers inside out and so the best strategy for one, may not be necessarily the best for the other.
Other factors that come into play when deciding how to approach a race include the nature of the circuit. The first one or two turns can be crucial after the race start when the field’s bunched up, adrenaline’s high and nothing’s quite up to temperature. If the run down to turn one’s short and the corner tight, a team might prefer to go all out in qualifying to be at the front and in relative safety, over a seemingly preferable race strategy that might have them on alternate tires but further down the pack, like Webber did on Sunday. While Vettel got through the first few turns in the clear and unscathed, his teammate got caught up with other cars and compromised his original plan just a little bit.
The statistical chance of a safety car at any particular circuit can have a huge impact on deciding a team’s race decisions. The chance of the safety car playing a part generally diminishes after the first two laps of any race. In India, those who started on option, like Vettel, would’ve benefited had that happened early on, enabling them to pit and ditch the soft tire, spending the rest of the race on mediums.
When Webber stopped on lap 29 today, he took soft, option tires, perhaps not the ideal tire for that part of the race, but he did it with a safety car in mind. If an incident had occurred, he too could’ve used the ‘free’ pit stop to switch back to the prime and finish the race on them. If he’d taken primes at the stop and the safety car had then come out, it would’ve ruined his Grand Prix as he’d have been forced to stop and take options, having not yet used them, and been left with an unmanageably long last stint.
In hindsight this was over-cautious. In the three years we’ve been racing in India, the safety car hasn’t yet made an appearance and at that middle stage of the race, it was highly unlikely it was going to. His fastest way to the end was to stay on primes and take the new options for a very fast, but short final stint, when the car was at its lightest and the field at its most stretched. In the end it was academic as he retired with an alternator failure.
Weather; track evolution; the amount of time lost in pitlane for each stop; the car’s characteristics like top speed or traction and many other parameters are all carefully considered before heading into qualifying. Of course depending on the outcome of Saturday afternoons, the whole thing needs looking at again, the simulation models updated with grid positions, another look at the forecasts, start performance and so on.
Many people, both at the track and back at the team’s European bases work through the night to give the drivers and engineers the best possible scenarios before Sunday’s race, but once the lights go out it’s a constantly morphing model and the team need to be able to react as the race unfolds.
Often it’s the ability to think on one’s feet, that sets a good team apart from a great one.
